Re: gold chloride

I think that it all depends on where you are and how much you, or a party of
friends and colleagues, can get together to buy at a time. It would be very
useful to learn your conclusions as to comparative costs.

As students on my workshops tend to buy rather a lot of precious metal salts,
I can get good prices. I will be running some workshops covering cyanotype
rex and chrysotype rex where I will be able to supply the salts inexpensively,
(if anyone is interested let me know). But supplying chemicals, as such, is not
my business.

In the UK One should be able to get gold salts through Silverprint through
the Speedibrews part of the business, and in the US through Bostick and
Sullivan. It is also worth checking to see whether Johnson Matthey have an office in
your area.

As to making chemicals, I have used the making of ferric oxalate on my
workshops as a means of demonstrating that chemistry is not something for magicians
in pointy hats who have an entry to the mysteries, but something no more
complex chemically than making a cake, At the time ferric oxalate was difficult to
get but now B&S sell good stuff cheaply.
